Improvning Measurement of Fat in Feed
To correctly determine fat in Feed a simple extraction, crude fat determination, might not be sufficient. Crude fat is the fat that can be extracted directly from a sample using only solvent. Often Hot Solvent or Soxhlet Extractors are used. However, some food matrices such as extruded cat and dog foods, oat based foods and some encapsulated oils require acid pre-treatment to give a correct fat measurement.
Acid pre-treatment, i.e. acid hydrolysis, is a separate step in total fat determination and therefore an additional risk for errors and mistakes. Methods are constantly being improved and Cargill and AOCS have as late as 2012 released new updates on these standards.
OPSIS LiquidLINE is also working actively to improve the reliability of these procedures. That is why we have introduced a Total Fat solution, which reduce the need for moving samples. Having one unique HydROC filter, which works during both Acid Hydrolysis and Hot Solvent Extraction, sample transfer errors are totally eliminated. Additional batch handling of samples with racks simplifies the procedure. Please read more at Fat determination or contact us for more information.
